Abstract

L'invention concerne un ensemble réfléchissant à panneaux plats permettant de recevoir et de focaliser des signaux de micro-ondes incidents possédant une certaine longueur d'onde (?). Cet ensemble comporte une série de surfaces réfléchissantes adjacentes, qui présentent respectivement un décalage de points focaux séparés d'une longueur d'onde ou d'un multiple de la longueur d'onde dans une longueur focale. Lorsqu'un signal de micro-onde incident touche l'ensemble réfléchissant, chaque onde réfléchie est dirigée vers le point focal de la surface réfléchissante respective et elle est recueillie par le filtre de bande de faible bruit. Chaque onde réfléchie arrive au niveau du point focal de la surface réfléchissante en phase avec un autre rayonnement réfléchi. Toutefois, la résolution spatiale des points focaux permet de diminuer les interférences déconstructrices entre les rayonnements réfléchis. Dans un autre mode de réalisation, l'ensemble réfléchissant à panneaux plats est élaboré pour réfléchir un rayonnement incident en phase, de telle façon que des signaux de micro-ondes réfléchis par chaque surface réfléchissante arrivent au niveau d'un point focal commun en phase.
